摘要：Homopolymers and copolymers which have an average molecular weight of atleast 2000 and which contain at least 5 mole %, relative to the polymer, of at least onestructural element of the formula I or II ##STR1## in which and R' are independentlyalkylene, cycloalkylene, aralkylene or arylene, R.sup.1 is halogen, nitro, alkyl, alkoxy,alkylthio, phenyl or aralkyl, R.sup.2 is a direct bond, --O--, --S--, methylene, carbonyl oralkylidene, R.sup.3 is hydrogen, aroyl or defined as R.sup.1, and as integers a is 0 to 3, b is0 to 4, c is 0 to 5, d is 0 to 5 and q is 0 or 1
The polymers are sensitive to radiation and can be used for the production ofprotective coatings or photographic relief images.
